A calendar is a list of posts you can finish
Put the niche in your own words ("sourdough for people in small kitchens", not "food"). Choose the weekdays you already have time, not the weekdays a growth thread told you to use. Four weeks is long enough to see a repeat and short enough that you are not planning a quarter you will ignore.
Each slot has one job. Teach is a step. Story is a specific attempt, including a failed one. Proof is a before and after where only one thing changed. Invite asks for one question you will answer next. If a generated line is generic, rewrite the noun. Do not add a second topic.
Put it somewhere you will see it
Download the .ics file and import it into Google Calendar, Apple Calendar, or Outlook. The event title is the post title. The description is the hook and the caption job. Copy Markdown instead if you keep the plan in a notes app.
Leave the posting hour off the file on purpose. This tool does not know when your audience is online. Set the hour from the posting-time tool or, better, from the platform's own audience chart, after the topic is decided.
When you also publish on YouTube
Use one of the week's slots as the long video and let the others cut a single point out of it. The paid Creator Climb calendar does this from your real upload weekdays and writes a thumbnail brief per slot. The free calendar is the right place to start if you do not have a channel connected yet.
